Abstract (en)
[origin: US9496879B1] Methods, apparatus, and systems for data communication over a multi-wire, multi-phase interface are disclosed. A method of data communication includes configuring a clock recovery circuit to provide a first clock signal that includes a pulse for each symbol transmitted on the interface, where symbols are transmitted on the interface at a first frequency, adjusting a loop delay of the clock recovery circuit to modify the first clock to have a second frequency that is no more than half the first frequency, where the clock recovery circuit generates a pulse in the first clock signal for a first of an integer number of symbols and suppresses pulse generation for other symbols in the integer number of symbols, configuring a clock generation circuit to provide a second clock signal, and capturing symbols from the interface using the first clock signal and the second clock signal.
